The weirdest thing about webcomic lists, on top of the fact they seem to pop up like Starbucks, is that they all have different rankings.

The only one I know that I don't see listed already is ComicRank. I'm not sure if it's technically a comic list, but I get a mild amount of hits from it, plus its ranking is based on traffic so you don't have to beg people to vote for you. I guess that could be a bad thing too, though.
